However, while a previously-released piece of concept art from Infinity War had made it look like Mjolnir's destruction would be permanent, a new set photo makes it look as though the opposite might be true. Posted by The Russo Brothers through their official Instagram page, the image shows Joe Russo directing while filming at the Durham Cathedral, which was used in the Harry Potter movies. But standing behind Russo is a Priest holding the legendary hammer. With a caption that only reads "Worthy," there isn't much explanation for the hammer's presence on the set either. Check out the photo for yourself down below:

The location itself looks like it could fit in well with the previously-established Asgardian aesthetic, though, that doesn't explain why there would be a Priest on the set, especially if it's an actor in costume. And with no explanation for why and how Mjolnir is there, still completely intact, it's hard to know where and how this moment in the film factors into the actual story of Infinity War.

There is the possibility that this is a flashback, with Thor heading back in time thanks to the powers of Benedict Cumberbatch's Doctor Strange, in an attempt to recover Mjolnir before it was broken by Hela, but that's about as speculative as it gets. This also seems to go against the first piece of concept art that was released for Infinity War, which saw Thor fighting alongside Bradley Cooper's Rocket Raccoon, while wielding a weapon that did not look at all like Mjolnir. So at this point, it's impossible to know what exactly is happening in this photo, or why Mjolnir is included in it - but with a little less than a year to go until Avengers: Infinity War hits theaters, there's still plenty of time to speculate and try figuring it out.
